Application filed September 14 1922. Serial No. 588,200.

To all whom it may concern.

Be it known that I, EMIL AHo, a citizen of the United States, residing at 'Gwen, in the county of Clark and State of Wisconsin, have invented certain new anduseful Improvements in Graders, of which the following is a specification. v

This invention relates to improvements in graders for use in leveling newly broken land, although obviously they may be used in road making or for other purpose. One object is to provide a device of this class that can be operated by one person who may, at the same time, drive the draft animals that pull the device and regulate the grading blade. Simplicity, durability of construction and efliciency in operation are objects attained.

With the foregoing and other objects in view the invent-ion consists in the combination and arrangement of parts to be hereinafter fully described, pointed out in the appended claim and: illustrated in the accompanying drawing which forms a part of this application and in which-- Fig. 1 is a side view of a grader constructed according to my present invention.

Fig. 2 is an end View partly in section.

Fig. 3 is an enlarged'fragmentary View in perspective.

Like reference characters denote corresponding parts throughout the several views.

The reference numeral 1 denotes a vehiole body provided with the front wheels 2 and rear wheels 3, the floor 4: of the vehicle being formed with a large perforation or opening 5, said body being provided also with a seat 6. If preferred the floor 4: may be entirely eliminated in the construction of the vehicle. V-shaped supports each formed of the beams '7, 8 connected together are secured to and depend from the sides of thev vehicle body, the beams 7 being. provided with the castings 9 that serve as bearings for the ends of the transversely extending double crank shaft 10, and the beams 8 being connected by and supporting the transversely extending beam 11 to which the brackets 12 I are'secured that are pivotally connected by links 13 to the rod 14 of the blade 15.

While the link 13 pivotally engages the rod 1a the blade 15 is fast to said rod as are also the sleeve ends of the links 16 which links are pivotally connected to the T-links 17 the sleeved cross-heads of which are fast to the shaft 10. Each link 16 is formed with a head 16 which has a bearing against the T-links 17 As the shaft 10 is oscillated the stems of the T-links oscillate in the arc of a circle of which said shaft 10, at its point of engagement by a T-link, is the center and the heads 16 of links 16 bearing against the T-links position the blades more or less deep in the loose earth.

With the shaft 10 in such position that its crank portions 18, 19 are approximately in a vertical plane the cutting or free edge 20 of the blade 15 extends well below the ground line as shown in Fig. 2. The operator from his seat 6 by keeping his feet upon links for said blade pivotally connected to said brackets, and sectional adjusting and supporting links for said blade pivotally connected to each other and made fast to said double-cranked shaft andblade.

In testimony that I claim the: foregoing as my own I have hereto afiixed my signature in thepresenceof two subscribing wit nesses.
